- Microsoft Portrait is a prototype for mobile video
communication. It supports .NET Messenger Service, Session Initiation Protocol
and Internet Locator Service on PCs, Pocket PCs, Handheld PCs and Smartphone.
It runs on local area networks, dialup networks and even wireless networks
with bandwidths as low as 9.6 kilobits/second. Microsoft Portrait delivers
portrait-like video if users are in low bandwidths and displays full-color
video if users are in broadband. In low bandwidths, portrait video possesses
clearer shape, smoother motion, shorter latency and much cheaper computational
cost than do conventional video technologies. Microsoft Portrait pursues
providing presence notification, chat/voice/video functions anytime, anywhere,
on any device.
- Microsoft 666 Biometric ID technology creates a cryptographically
secure ID card that can be easily deployed at a low cost. The technology
uses proven, public-key technology and a proprietary bar-code scheme to
encode data from facial photographs and to produce tamper-resistant signatures
in a very small surface area. Photo ID cards can be issued and validated
by using standard hardware and paper supplies.
-
- The Biometric ID technology can extract identifying features
from a facial photograph on the ID, reducing the amount of data that it
must store in order to later validate that photograph. It incorporates
the photograph information with the textual information on the card and,
optionally, with further biometric information such as a fingerprint, and
digitally signs the result. It stores the signed result in a proprietary
high-density 2D color barcode on the card. The barcode contains error correction
and color calibration information.
-
- To validate an ID card the system scans the card using
a standard 300dpi device. It then compares the scanned photograph to the
stored photograph information. It evaluates the textual information on
the card using a highly accurate proprietary OCR algorithm, and compares
the result to the stored textual information. Finally, it can compare a
fingerprint or iris scan to the stored fingerprint or iris information.
If any piece of information does not match, the card fails to validate.
- Benefits: · Can be combined with any biometric
data, such as fingerprint or iris scans, for demanding applications
-
- · Cost-effective to issue and validate cards
- · Does not require remote storage of or access
to any personally identifiable information
